There's nothing illegal about the media discussing your case. In fact most media outlets don't hold back many details about the accused, because it's all public information that anyone curious about it can get from the court clerk's office for free and with no reason specified.
If jury selection hasn't started yet, then asking each juror about what they might know about the case is a pretty standard question that any competent defense attorney would be asking, even without knowledge of media coverage. If they already know about the case and say they can't put that knowledge aside when rendering a verdict, they are almost always dismissed. If you're concerned your defense attorney isn't aware of the media coverage, that's something you need to bring up with them.
If jury selection already took place, and nobody bothered to ask them if they had prior knowledge of the case, then there's pretty much nothing you can do. A judge might ask the jury if anyone's seen the coverage, but it usually results in nothing happening. The media talking about your case is not grounds for a mistrial; it's rarely even grounds for a change of venue. Getting a mistrial would require you to prove a specific juror engaged in misconduct somehow.
